PLATFORMBOOKING & CHANNEL MANAGEMENT

Keep Every Booking Channel In Sync, Even When There's No API To Plug Into

Property and hospitality businesses run across Airbnb, Booking.com, and direct channels at once. We build the sync layer that keeps availability, pricing, and guest access consistent everywhere, and we've solved this even when a platform's API didn't exist yet.

See What We Build

Real client work

Multi-channel integration for a hospitality platform.

No API? No problem

We engineered access to Airbnb data before its API existed.

Smart access

RemoteLock and facial recognition check-in, tied to booking data.

Multi-channel

Airbnb, Booking.com, and Beds24 kept in sync.

What We Actually Build For Booking & Hospitality Platforms

The hard part isn't any single integration. It's keeping several booking sources and the physical access to a property all pointed at the same truth.

CHANNEL SYNC

OTA & channel manager integration


Syncing availability, rates, and reservations across Airbnb, Booking.com, and channel managers like Beds24, so a property is never double-booked.

ACCESS

Smart lock integration


RemoteLock integration that generates unique, time-sensitive door codes per guest, tied directly to the reservation window.

CHECK-IN

Facial recognition check-in


Contactless check-in using AWS Rekognition, connected to guest and booking data so identity and access are verified automatically.

DATA EXTRACTION

Working without an official API


When a platform hasn't released the API you need yet, we engineer a reliable path to the data, then migrate cleanly once an official option exists.

MESSAGING

Guest messaging consolidation


Pulling guest communication from multiple channels into a single inbox, so hosts and property managers aren't checking four apps.

REPORTING

Cross-channel reporting


Unified occupancy, revenue, and booking-source reporting across every channel a property is listed on.

Why This Integration Work Is Harder Than It Looks

Booking platforms weren't built to talk to each other. Every property manager running multiple channels ends up needing custom work to close that gap.

Double bookings are a direct cost

Without real-time sync across channels, the same date can get booked twice, which means a cancellation, a refund, and a guest you have to relocate.

Not every platform has a public API

We've been in exactly this position: needing Airbnb data before Airbnb had released the endpoint for it, and building a reliable path to that data anyway.

Guest experience depends on access working

Contactless check-in only works if door codes and facial recognition are generated and revoked exactly on the reservation window, every time.

"I hired NUS to work on our existing Airbnb management software. They communicated well with our team and provided high quality work in short time. Their English skills were also great in both verbal and writing. In the end I worked with multiple developers, business analysts and quality control in NUS over 3.5 years. I'm very satisfied with their service. I think they are very good at building cloud based software and mobile apps."

How An Engagement Usually Starts

We start with the specific channels and access systems you're running today, not a generic hospitality integration checklist.

AUDIT

We map every channel and access system in play

01

A review of the OTAs, channel managers, and physical access systems your properties currently run on, and where API access exists or doesn't.

SCOPE

You get a concrete plan, not a vague proposal

02

Which channels sync automatically, which need a custom data path, and how guest access ties back to the booking record.

BUILD

Built and tested against live channel data

03

Sync logic is validated against real booking flows in staging, including edge cases like same-day cancellations and overlapping holds.

SUPPORT

Ongoing support as channels change their APIs

04

When a platform updates or finally releases an official API, we migrate your integration without disrupting live bookings.

Questions Clients Usually Ask

What booking and channel manager platforms have you integrated with?

PlusMinus
Airbnb, Booking.com, and Beds24 as a channel manager, alongside RemoteLock for smart access and AWS Rekognition for facial recognition check-in, built for a multi-property hospitality platform managing bookings across several OTAs at once.

What if the platform we need to integrate with doesn't have a public API?

PlusMinus
We've handled exactly this. When Airbnb's official API wasn't yet available for the functionality a client needed, we engineered a custom solution to extract booking details, host information, and guest messages directly, then migrated cleanly to the official API once Airbnb released it. We don't treat a missing API as a dead end.

Can you sync availability and pricing across multiple booking channels?

PlusMinus
Yes, this is the core problem channel manager integrations solve. We sync availability, rates, and bookings across platforms like Airbnb and Booking.com so a property doesn't get double-booked from two channels at once.

Can you add contactless check-in to an existing booking platform?

PlusMinus
Yes. We've integrated RemoteLock to generate time-sensitive door codes per guest, and AWS Rekognition for facial recognition check-in, both connected to the underlying booking and guest data so access is automatically granted and revoked around the reservation window.
